I have my RoR Application with Rails 3.1.3
I try to run "rake ts:config", but it always return error "At least one
field is necessary for an index", any body can help me to solve this
problem?
I think I already define index in my model, Training, but when I run rake
task to generate ts configuration, it always return error.
Here is my model:
# == Schema Information
#
# Table name: trainings
#
# id :integer(4) not null, primary key
# user_id :integer(4)
# name :string(255)
# description :text
# created_at :datetime
# updated_at :datetime
#
class Training < ActiveRecord::Base
# attributes
attr_accessor :training_tags
# relations
belongs_to :user
has_many :training_tag_relations
has_many :tags, :through => :training_tag_relations
# return flatten tag in array
def flatten_tag
tags.map { |t| t.name }
end
# call back after create
after_create :create_training_tags
# define index for mapping
define_index do
# field
index :name, :sortable => true
index :description
index tags.name, :as => :tag_name
# attribetus
has :user_id, :created_at, :updated_at
end
end
